Top 10 Most Useless Math Concepts

You learn a lot of supposedly important stuff in mathematics. PEMDAS, algebra, sales tax...then there are some lessons that do nothing to expand your understanding of the world. Will you need them in real life? Probably not. Maybe if you're an engineer or computer scientist, but for everything else in life...likely not. So now that I've dragged on long enough about stuff you're not even gonna read, here are the math concepts you least need in life.

The Top Ten

1 Geometric Proofs

You don't really need to know how to prove that one line is parallel to another. The steps in proofs are absolutely useless, and don't need this in the real world. I mean, who draws two triangles and tries to prove that they're parallel? That's right, obviously not you. And probably not your friend. Or your dad. Or your grandpa. - naFrovivuS

Ah yes, proofs. A beautiful waste of time. "Prove That these two triangles are congruent! Then sit there for 12 hours writing each step in proving it. Never mind the fact that you will never use this in your life." - DCfnaf

It's the concept that you need. You don't need to prove a thing that is already proven. In my whole school life I have never found the uses of geothermic proofs except for pain in the @$$. - zxm

Is it really just enough to accept things as "true" without learning why and validating the facts? Scholastics should be designed to enhance the furthering of potential - whether or not the individual chooses or cares to expand in that direction. - Billyv

3/4 of math is useless

2 Polynomials

How exactly do you do these again? I don't really know how exactly they apply to the real world. Maybe we're constantly surrounded by them and just shun them out, but it's not exactly something to consider. Polynomials seem to be a huge issue for students, and are just a roadblock you could do without. - naFrovivuS

3 Multivariable Functions

A sub-branch of calculus, this seems to have even less use than calculus. Unlike basic calculus, which has use for some things in life, I don't know if it's even used in engineering or architecture at all! If calculus II isn't mind grating enough, hope calculus III puts you in the grave. - naFrovivuS

4 Calculus

They say it's important for modern science and engineering. However, it's been seen that in modern computer science they make almost no use of calculus, rather discrete maths instead. Not to add that with every generation there seems to be less people wanting take up computer science. Oh well! - naFrovivuS

5 Logarithms

Your points are well taken. Particularly at the high-school level, it's nearly impossible to gain comprehension of higher math given the limited instructional time available. It takes months if not years to fully grasp the underlying concepts and theories alone. And little if any time is spent imparting understanding of the real-world applications of such disciplines, which would go far in generating sufficient interest to apply oneself.

I really don't know how to imply this to a regular daily life. Heck, I don't even understand how to do these at all! Like most would say, it's important if you are an engineer/scientist, but if you're aiming towards different things, logarithms are probably something to skip. - naFrovivuS

6 Algebra II

Algebra II, the common core lesson that results in several dropouts every year. Yes, I covered branches of Algebra II, but you know, there are other branches that lead to nothing but stress you shouldn't have to learn. So yes, it can get its full mention as a useless topic that really shouldn't be mandatory to pass college. - naFrovivuS

7 Polynomial Long Division

I've managed to acquire much easier ways to divide polynomials. But let's not get into that, considering I'm not a math professor. Point being, you don't need to do all those long steps to divide polynomials, considering there are easier ways to get through that you hopefully learned in your freshman year of high school. - naFrovivuS

8 Point Slope

I honestly don't know where or when I'll need to use this. - isaaonrtdmtr

Yes. If I ever use this in my life... why would you need to graph lines and how does knowing the slope help you unless you are maybe a desginer or engineer, that's pretty much it. - Lucretia

Okay, so once again, something important for engineering, but let's just face it. I don't really know why it's a mandatory course in middle school, considering its little use in the real world. There isn't much to it. y=mx+b seems easy enough to learn. But expanding on this concept, like a lot of things on this list, is just a painful mind grating task that isn't much use to a lot of other things in life. - naFrovivuS

9 Quaternions

This used to be something that was incredibly useful for expanding your understanding of complex numbers. Sadly, this concept has been long forgotten, and other methods of understanding complex numbers have been developed over the time. This could be useful, had it not be forgotten. - naFrovivuS

10 Long Division

I'm only putting this at the bottom of the list because it can be only slightly useful. If you don't have or are not allowed to use a calculator, this could help to some extent. But because most schools are allowing calculator use, you could say long division could very well be obsolete. However, for an SAT or ACT, hope you learned long division. - naFrovivuS

It's kinda useful, but not all that much. - isaaonrtdmtr
